What is vitamin B6 and what does it entail for our diet?
Vitamin B6 is unique as it is involved in the metabolism of the three macronutrients: protein, lipids and carbohydrates. The enzymes involved in the metabolism of the amino acids use pyridoxal phosphate (a biologically active form of pyridoxine, once absorbed), as a cofactor. Because of the extensive nature of these reactions, the requirement for this vitamin is related to the protein content in our diet.
Vitamin B6 is a water-soluble vitamin, so it must be replenished daily as the body cannot store large amounts, being the major reservoir organs: the liver, brain, kidneys, spleen and muscles. Muscles contain 80-90% of vitamin B6 stores.
Vitamin B6 deficiency affects as follows:
- Nervous system: irritability, nervousness, inability to concentrate, confusion, changes in mood.
- Circulatory system: alterations in the synthesis of red blood cells.
- Skin: seborrheic dermatitis, rashes.
Paul Gyorgy identified vitamin B6 as a factor different from riboflavin and the preventive factor of pellagra (niacin). The isolation of crystalline vitamin B6 was reported by Gyorgy and Lepkovsky, calling this compound pyridoxine.
